Word History: Today's Good Word was taken from Latin vibran(t)s "swaying", the present participle of vibrare "to sway, swing". The past participle of the same verb, vibratus, was snitched by English for vibrate and its family of words: vibrator, vibrative, vibration, etc. Latin took its word from the Proto-Indo-European root weip- "to turn, sway", which also went into the making of Sanskrit vepate "it flutters". In the Germanic languages it became Danish vippe "to flip", Dutch wippen "to hop, skip", and English wipe, waif and waver.
